| Carcinogenicity_EU_PPP | - | - | - | The Scientific Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food (the Panel) is asked to advise the Commission on the implications for human health of chemically defined flavouring substances used in or on foodstuffs in the Member States. In particular, the Scientific Panel is asked to evaluate 15 flavouring substances in the Flavouring Group Evaluation 09, Revision 1 (FGE.09Rev1), using the procedure as referred to in the Commission Regulation (EC) No 1565/2000. These 15 flavouring substances belong to chemical groups 8, 25 and 30, Annex I of the Commission Regulation (EC) No 1565/2000. The present flavouring group evaluation deals with 15 secondary alicyclic saturated and unsaturated alcohols, ketones, one hemiketal ester and esters containing secondary alicyclic alcohols. The flavouring substances are structurally related to 24 flavouring substances evaluated at the 51st, 59th and 63rd meetings of the Joint FAO/WHO Expert Committee on Food Additives (the JECFA). |
| Carcinogenicity_EU_PPP | - | - | - | Following a request from the European Commission, the European Food Safety Authority (EFSA) Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of 29 compounds (secondary alicyclic saturated and unsaturated alcohols/ketones/ketals/esters with ketals containing alicyclic alcohols or ketones and esters containing secondary alicyclic alcohols) belonging to chemical group 8. |
| Carcinogenicity_EU_PPP | - | - | - | Following a request from the European Commission,the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) was asked to deliver a scientific opinion on the implications for human health of chemically defined flavouring substances used in or on foodstuffs in the Member States. In particular, the Panel was requested to evaluate 21 flavouring substances in the Flavouring Group Evaluation (FGE) 9, Revision 5 (FGE.09Rev5), using the Procedure as referred to in the Commission Regulation (EC) No 1565/2000. These flavouring substances belong to chemical group 8, 25 and 30, Annex I of the Commission Regulation (EC) No 1565/2000. |
